Abstract
Three-dimensional modelling of a 3-3 piezoelectric structure was carried out using finite element modelling software. Hydrostatic figures of merit were calculated for structures with increasing amounts of interconnecting porosity. In addition to using air as the second phase, polymer fillers were added to the three-dimensional model in order to observe the effect of polymer Young's modulus on the piezoelectric properties of the bulk material. Results show that increasing the porosity has the effect of improving the hydrostatic piezoelectric properties for applications such as low frequency hydrophones.
